That is one heck of a man cave! You shoot the decor yourself? I bet the room sounds good too. That vaulted ceiling and plenty of soft furnishings. The panorama camera is very impressive too. I like the fact that you can drag the image around manually.

A woman that does eh? The way forward. I could see that a lot of thought had gone into acoustics. You pleased with the way it all sounds? I gave up with speakers in my main room as the dimensions and layout were hopeless. Hence headphones!

What does the "speed" of a headphone mean, and what of the Innerfidelity.com measurements is indicative of it? I know what it's supposed to mean, but how does one describe it? i.e. What do snare drums or cymbals sound like if they were from a "slow" headphone versus a "fast" one?

Does speed relate to how one perceives the soundstage and/or imaging?

Innerfidelity measures the impulse response and claims more oscillations/wiggles indicates a smaller soundstage, or was it imaging?Edited by miceblue - 11/1/13 at 9:34am

The term you may hear with a snare drum that I like to use is "snap", if you've ever been around a drummer hitting the snare at full power you can feel it physically, and while its not really possible to exactly recreate that feeling with a headphone, it is amazing how much of that feeling can be relayed through a good pair.

The stuff xnor said is pretty spot on as well.Edited by Muinarc - 11/1/13 at 11:02am

Or if a headphone reproduces the faster decaying overtones of an instrument louder, for example because of a treble boost, it's probably gonna be perceived as "faster".

The speed and timing relationship didn't really change though.

I could also think of high amounts of distortion mudding up the whole spectrum which could cause the decay of distinct tones to be perceived as faster (they would disappear earlier in all the added distortion products).
